Endress + Hauser Analog free chlorine sensor CCS51

Sensor for drinking water, pool and process water as well as utilities in all industries

CCS51 is a robust, low-maintenance sensor for free chlorine. It provides high-precision measurement with 

long-term stability in drinking water, 

pool and process water and ensures consistent disinfection monitoring even at low water volumes. 

The analog free chlorine sensor features extremely fast response times guaranteeing efficient process control and safe processes. 

CCS51 ensures continuity for the installed base of analog free chlorine measuring points.

Benefits

Fast response time (t90 < 25 s) provides accurate process view and enables prompt reaction to process 

changes as well as efficient process control. Increased process safety: precise and long-term stable measurement 

ensures consistent process monitoring and allows for individually adapted disinfectant dosing.

The low-maintenance, amperometric sensor reduces the cost of ownership of the measuring point, 

particularly compared to colorimetric measuring systems.

Connection to the Liquisys chlorine transmitter ensures continuity for the installed base of analog free chlorine measuring points.

Field of application

CCS51 is an analog free chlorine sensor for skid builders and end customers. It measures reliably in:

Drinking water - to ensure reliable disinfection

Food - to guarantee food safety and provide hygienic packaging and bottling

Utilities - to detect the absence or presence of free chlorine

Pool water - to dose disinfectant efficiently
